I presented a summary of the methodologies that we have assembled to treat ion-atom and ion-molecule collisions. Some of these methodologies can deal with systems with more than two active electrons, which is particularly important for the intermediate range of collisional energies (around 1 keV/u). At the same time, we have developed methods to treat complex systems (many electrons) using one-electron wave functions and/or classical mechanics.

A chart of codes with a brief summary of their capabilities was presented, alongside a few examples showing recent results on isotope effects in beryllium collisions with hydrogen and collisions with molecules like CH4. The possibility of other users using the codes was also discussed.
